130.Section 17(1) contains definitions of expressions used in the Act.
131.Subsection (2) confers the power to prescribe in regulations the circumstances in which persons are to be treated, or are not to be treated, (a) as members of the same household or (b) as severely disabled. In practice, questions whether persons are members of the same household arise in only two cases:
the determination of whether two persons are a "married couple" (see the definition in section 17(1)); and
the determination of whether the conditions in section 12 (polygamous marriages) are satisfied in any particular case (seesubsection (1)(c) of that section).
